Septin-binding domains of Bud4 and Hof1 have distinct subunit preferences. (A) Cells (strain GFY-42) expressing Cdc10-mCh and coexpressing Bud4(623-774)-eGFP under the control of the BUD4 promoter from a CEN plasmid (pGF-IVL1095) were grown and visualized as in Figure 4A. (B) Diploids (287–291) expressing Bud4(623-774)-(linker)33-β11 from its native promoter on a LEU2-marked CEN plasmid (pGF-IVL1082), the β10-(linker)18–tagged versions of each of the five mitotic septins (left), a URA3-marked CEN plasmid (pGF-IVL1005) expressing GFPβ1-9 from the GAL1/GAL10 promoter (unpublished data), and either Cdc10-mCh or Cdc11-mCh (as indicated) were selected on SD-Ura-Leu medium, grown, induced with galactose, washed, and imaged as in Figure 1B. (C) Quantification, as in Figure 1C, of the data in B. (D) Cells (strain GFY-42) expressing Cdc10-mCh and coexpressing eGFP-Hof1(293-355) under the control of the HOF1 promoter from a CEN plasmid (pGF-IVL1110) were grown and visualized as in Figure 4A. (E) Diploids (292–296) expressing Hof1(293-355)-(linker)33-β11 from its native promoter on a LEU2-marked CEN plasmid (pGF-IVL1082), the β10-(linker)18–tagged versions of each of the five mitotic septins (left), a URA3-marked CEN plasmid (pGF-IVL1005) expressing GFPβ1-9 from the GAL1/GAL10 promoter (unpublished data), and either Cdc10-mCh or Cdc11-mCh (as indicated) were treated and examined as in B. (F) Quantification, as in Figure 1C, of the data in E.
